Hello Bjorn

As there are uses with spaces, this would be better as:
if ($line =~ /\bMODULE_LICENSE\s*\(\s*($String)\s*\)/) {

Why add "Proprietary" ?
This is the list I get in the current tree:
(after collapsing spaces in a few places)
5920 MODULE_LICENSE("GPL")
1211 MODULE_LICENSE("GPL v2")
187 MODULE_LICENSE("Dual BSD/GPL")
37 MODULE_LICENSE("GPL and additional rights")
26 MODULE_LICENSE("Dual MPL/GPL")
1 MODULE_LICENSE("Dual MIT/GPL")
1 MODULE_LICENSE("BSD")

I'd write this on 2 lines in the same fashion as
all the other warnings:
WARN("MODULE_LICENSE",
"unknown module license
$extracted_string\n" . $herecurr);
Other than those minor issues, it seems sensible enough.
thanks, Joe
